| 摘要: |
| [目的]筛选出适合饲养亚洲玉米螟Ostrinia furnacalis(Guenee)的最佳饲料配方,以期改进亚洲玉米螟的饲养技术,为进一步研究亚洲玉米螟人工大量繁殖技术提供依据.[方法]在周大荣新7号配方人工饲料的基础上,设计了4种不同的人工饲料配方饲养亚洲玉米螟,研究4种人工饲料配方对亚洲玉米螟生长发育、存活、繁殖和种群增长的影响.[结果]在试验设计的4种不同饲料配方中,配方2(玉米面86 g/kg,大豆面86 g/kg,Vc 2.9 g/kg,琼脂11.5 g/kg,酵母粉51.6 g/kg,山梨酸2.9 g/kg,葡萄糖43 g/kg,水716.2 g/kg)的饲养效果最好,亚洲玉米螟的化蛹率、羽化率、成活率、净增殖率、内禀增长率和周限增长率均极显著高于其他配方,平均世代周期和种群加倍时间最短.配方1和配方3的饲养效果次之,配方4的饲养效果较差.[结论]饲料对亚洲玉米螟生长、发育有重要影响,配方2是适合亚洲玉米螟生长的最佳配方. |

| Abstract: |
| 【Objective】 The research studied the influence of 4 artificial fodders on the growth development,survival,and reproduction of the Asian corn borer(ACB).【Method】 Life table was built in the laboratory.Four different prescriptions of artificial fodders were used to raise ACB and were experimented on the basis of former prescriptions.【Result】 Results showed that prescription 2 （maize flour 86 g/kg,soybean flour 86 g/kg,Vc 2.9 g/kg,agar-agar 11.5 g/kg,yeast powder 51.6 g/kg,sorbic acid 2.9 g/kg,glucose 43 g/kg,water 716.2 g/kg）displayed the high efficiency in 4 tested prescriptions by observing life indexes of ACB related with growth development and reproduction.Next were prescription 1 and prescription 3,both displaying almost the same efficiency.Prescription 4 was not suitable for breeding ACB compared with former 3 prescriptions.【Conclusion】 Growth development,survival,and reproduction of the Asian corn borer (ACB)/Ostrinia furnacalis are remarkably influenced by nutrition of foodstuffs.Prescription 2 is fit to Ostrinia furnacalis's growth. |
